Using 60-GHz frequencies for wireless communication faces the challenge of oxygen absorption, which leads to signal attenuation and reduced range. These frequencies are best suited for short-range links, typically less than 100 meters, which can be effective in densely populated urban areas.
However, optimal strategies for utilizing these transmissions in city environments, including the ideal placement height of access points to circumvent signal scattering by obstacles, are still areas requiring further exploration and understanding.
